WHAT IS FR4 MATERIAL IN PCB? (FR4 Electronic PCB Assembly)
The majority of electrical engineers, as well as those working with circuit boards, know much about FR4. The majority of rigid boards are constructed with FR4 as their base material. Many people don’t even know what FR4 is, let alone know why it’s the most often used PCB base. After constructing the Circuit board, your task is far from finished. The board still needs to be put together by attaching electronic parts to it. When you’ve finished, your PCBA is complete.
FR4, also written as FR-4, is both a name and a standard rating. The name is applied to the fiberglass-reinforced epoxy-laminated sheets used in printed circuit board manufacturing. However, the name also functions as a grade used to rate epoxy laminate sheets. The designation essentially indicates the base quality of a laminate sheet, meaning a variety of sheet materials and designs fall under the FR4 rating. The “FR” in the name stands for flame retardant, while the 4 differentiates the material from others of the same class.
The material widely referred to as FR4 is a composite structure. The most basic layer of the material is fiberglass woven into a thin, cloth-like sheet. The fiberglass gives FR4 its necessary structural stability. This innermost fiberglass layer is then surrounded and bound by a flame-resistant epoxy resin. This resin is what gives the material rigidity, among its other physical properties.
